摘　　要：将Hoek-Brown强度准则应用于三维显式有限差分法程序——FLAC3D中,对围岩变形、破坏过程进行了数值模拟研究,以使即将掘进的11504上顺槽进行科学的支护设计,指出新的设计方案经过现场试验及研究取得了良好的经济效益。The paper indicates the Hoek-Brown strength criterion is adopted in the three-dimension explicit finite difference method program FLAC3D, illustrates the numerical simulation research in the surrounding deformation and damage＇process, in order to have a supporting design for the tunneling 11504 crossheading, and points out the new design scheme can achieve better economic benefits by the field experiment and research.
